METHOD determining the indications for operative delivery in breech presentation

摘要

A method of determining indications for operative delivery breech fetal comprising identifying degree extension fetal head using an ultrasonic method of determining the angle between the occipital bone and the spine axis, characterized in that in the presence of 3 degrees of extension of the fetal head further comprises determining systolic and diastolic ratio of blood flow velocity in middle cerebral artery (SDOsma) and the arithmetic mean of systolic and diastolic blood flow velocities in the relationship right and left vertebral arteries Barrier-(SDOpa) fetal then calculated ratio SDOsma / SDOpa - cerebro-spinal coefficient (CPC), and while maintaining this value before delivery is less than 1.0, is defined as the indication for operative delivery planned.
